Onyx and Talc

In dark my heart

 Two pieces

Onyx

 Talc

Softly slicing

Sharply powdering

Fighting

 Crushing

Talc can't touch the onyx

 Onyx can't crush the talc

Inside       bleeding

Broken    aorta

Some hearts can't contain two pieces

Sometimes I think

My heart can't

Either

  Glitter    Glow

Pretty Luv Falters

  Take my heart

    In my hand

      Slivers in

         hand

           O
